Just got my official acceptance letter sent to my email today! There are no real instructions in it, but it did provide my student ID. I also got a little postcard type thing in the mail earlier this week (from the student financial aid office) and it has instructions on how to check your status and set up your UTEP email account with your student ID #.
To check your financial aid status/scholarships/holds/admission status go to: https://mystatus.utep.edu
To set up your UTEP email account go to: https://newaccount.utep.edu
You'll need your student ID # to do both of these things. Hope this helps and I'd like to know if any of y'all get any further instructions on what the next step is in terms of advising and registration.
